Modelling and Comparing Shading Effects of 3D Tree Structures with Virtual Leaves
shadow model TLS LiDAR agroforestry QSM Prunus avium insolation shade cast
2023/12/6
Reduced solar radiation brought about by trees on agricultural land can both positively and negatively affect crop growth. For a better understanding of this issue, we aim for an improved simulation o...
Shading Promoted Theanine Biosynthesis in the Roots and Allocation in the Shoots of the Tea Plant (Camellia sinensis L.) Cultivar Shuchazao
Camellia sinensis L. Shuchazao 茶氨酸

TIANDITU (Map World) is the public version of National Platform for Common Geospatial Information Service, and the terrain service is an important channel for users on the platform. With the developme...
SHAPE AND ALBEDO FROM SHADING (SAfS) FOR PIXEL-LEVEL DEM GENERATION FROM MONOCULAR IMAGES CONSTRAINED BY LOW-RESOLUTION DEM
Moon DEM Shape and Albedo from Shading (SAfS) Monocular Image
2016/11/8
Lunar topographic information, e.g., lunar DEM (Digital Elevation Model), is very important for lunar exploration missions and scientific research. Lunar DEMs are typically generated from photogrammet...
The Assumed Light Direction for Perceiving Shape from Shading
Shape-from-shading light-from-above shape perception, Lambertian shading
2016/5/24
Recovering 3D shape from shading is an ill-posed problem that the
visual system can solve only by making use of additional information
such as the position of the light source. Previous research has...
Towards optimal relief representation from Mars imagery by combination of DEM and shape-from-shading
Mars imagery combination DEM shape-from-shading
2016/5/20
Described are experimental results of a first approach towards optimal shaded relief representation of the surface of Mars derived from Viking Orbiter digital imagery. The complex problem addresses ho...

In this contribution we describe an image-based framework for 3D surface reconstruction by a combined analysis of reflectance,polarisation, and sparse depth data. An error functional consisting of sev...
Shape from Shading is one of the methods used for shape recovery which exploits the fact that surface patches, having different
inclination relative to a light source are imaged with different bright...

Multi-image Shape-from-shading: Derivation of Planetary Digital Terrain Models Using Clementine Images
High-resolution DTM extraterrestrial surfaces reconstruction method
2015/7/8
In many cases, the derivation of high-resolution digital terrain models (DTMs) from planetary surfaces using only conventional
digital image matching is a problem. The matching methods need at least ...
